//==========================================================================// // Flowsquare+ parameter file... -- 2021R1.0 -- // //--------------------------------------------------------------------------// // You may directly edit this file, but follow below rules. Each // // parameter entry consists of three blocks divided by [SPACE] or // // double-slash(//). The order of these entries can be arbitorary. // // Example: // // 003:name 0.00123456789 // some explanation of the parameter // // ^^^^^^^^^ ^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ // // 1st block 2nd block 3rd block starts after (//). // //==========================================================================// ----- General Parameters ---------------------------------------------------------------------------------- 002:cmode 0 // Simulation mode. [0] Fluid simulation mode (constant density and temperature, suitable for gas and liquid single-phase flows). [1] Thermo-fluid simulation mode (variable density and temperature, suitable for gas phase flows). 003:ageFlag 1 // Whether or not including the age variable in the simulation. 004:parallel 2 // Level of parallelism. [0] Serial (no parallelism). [1] Two, parallelism=2. [2] Low, max(2, maxThreadsAvail/4). [3] Medium, max(2, maxThreadsAvail/2). [4] High, max(2, maxThreadsAvail). 005:domx 1400 // Nominal screen size (horizontal) during simulations. (unit: pixels) 006:nx 300 // Number of mesh points in x-direction. This number may be set independent from physical domain dimensions. 007:ny 180 // Number of mesh points in y-direction. This number may be set independent from physical domain dimensions. 008:lx 3.5 // Physical domain size in x-direction. (unit: m) 009:ly 2.1 // Physical domain size in y-direction. (unit: m) 010:sts 0 // Start time step. A new simulation starts from sts=0. To restart, sts should be a timestep at which dump data was output in the previous simulation. 011:latts 100000 // End time step. For simulations under a trial license, this is limitted. 012:nfig 10000 // Interval time step for image output. Result images are saved in the 'image' directory once in every 'nfig' time steps. Setting zero value disable image output. 013:nfile 10000 // Interval time step for dump data output. Result dump data are saved in the 'dump' directory once in every 'nfile' time steps. Setting zero value disable dump output. ----- Boundary and Initial Conditions -------------------------------------------------------------------- 015:presW 1.0E+05 // Mean pressure. Atmospheric pressure is 1.013E+5 (Pa). (unit: Pa) 016:uinB 0.0 // X-velocity component for the BLUE inflow boundry. If the value is set as '-', this boundary is slip boundary in x-direction. (unit: m/s) 017:vinB 1.0 // Y-velocity component for the BLUE inflow boundry. If the value is set as '-', this boundary is slip boundary in y-direction. (unit: m/s) 018:uinY - // X-velocity component for the YELLOW inflow boundry. If the value is set as '-', this boundary is slip boundary in x-direction. (unit: m/s) 019:vinY - // Y-velocity component for the YELLOW inflow boundry. If the value is set as '-', this boundary is slip boundary in y-direction. (unit: m/s) ----- Physical and Model Parameters ------------------------------------------------------------------------ 021:mu 1.8E-5 // Dynamic viscosity of the fluid. mu is approximately 1.8E-5 (kg/m/s) for the atmospheric air at 15~25 (deg.C). For water at 20 (deg.C), mu is 1.0E-3 (kg/m/s). (unit: kg/m/s) ----- Graphics & Visualization Parameters ------------------------------------------------------------------ 023:ndiv 16 // Interval mesh points between displayed visualization related objects such as vectors, streamlines and particles. #End of file
